1-4, An internal fuse clip insulating cover for a high voltage switch, comprising:
The insulation cover comprises an insulation cover body, wherein the insulation cover body comprises insulation plates 3 and 5 at two sides and arc-shaped plates connected with the insulation plates 3 and 5 at two sides, and the concave side of each arc-shaped plate faces the insulation plate;
A fixing groove 4, wherein one end of the arc-shaped plate is provided with a fixing plate extending from the inward concave side, and the middle part of the fixing plate is provided with the fixing groove 4;
the boss 1 is arranged on the arc-shaped plate, and the boss 1 is close to one end provided with the fixing plate;
Copper mother 2, the said copper mother 2 inlays in the said boss 1;
The insulating cover body, the fixing plate and the boss 1 are made of insulating materials.
In some embodiments of the present utility model, the insulating cover body, the fixing plate and the boss 1 are made of insulating rubber.
In some embodiments of the present utility model, the height of the boss 1 is not higher than the height of the fixing groove 4. As shown in fig. 2, the copper matrix and the boss are integrally horizontal and completely recessed.
In some embodiments of the utility model, the fixed plate is in height conformity with the arcuate plate.
In some embodiments of the utility model, the boss 1 is positioned in alignment with the fixing recess 4.
The fuse clip insulating cover in the high-voltage switch can be directly contacted with the transformer below the plane of the insulating cover. The insulating cover can nest fuse clips or conducting bars, so that the internal bare dew point of the switch is protected from short circuit faults, and meanwhile, the insulating cover is in a semi-open shape as a whole, and is used for opening the fuse clips during maintenance and facilitating the disassembly of fuses.
It can be seen from fig. 1 that the overall structure is divided into 5 aspects, wherein the copper busbar 2 is a copper product nested into the overall component, because the insulating part is made of rubber material for insulating treatment, but the rubber has ductility, which is unfavorable for fixing the insulating part to the fuse clip and the conductive copper bar, and the solid design of a nested piece made of copper is convenient for fixing the insulating part. The boss 1 is used for conveniently fixing the fuse wire conductive copper bar into the fixing groove 4 in a matched mode with the fixing groove 4 on one hand, and is used for perfectly wrapping the copper busbar 2 on the other hand, so that the integral fixing effect is achieved. The insulating plates 3 and 5 are sector-shaped (one side of the arc-shaped plate is an arc-shaped edge) so as to isolate the mutual interference between two adjacent phases and prevent the discharge phenomenon caused by the fact that the two phases are too close. The whole insulating cover can be respectively arranged on an upper fuse clip and a lower fuse clip of the fuse, the upper fuse clip is positively arranged, and the lower fuse clips are reversely arranged, and the upper fuse clip and the lower fuse clip are matched with each other in pairs to protect the clips at two ends of the fuse.
The utility model can protect the exposed node of the fuse clip in the switch cabinet through the insulating cover, and prevent the discharge phenomenon. According to the utility model, the copper bus is nested at the boss in the insulating cover and is clamped and fixed with the notch, so that the insulating cover is ensured not to be damaged after long-time use under the condition of ensuring the fastening of the insulating cover. The insulating cover is made of coastal corrosion resistant insulating rubber, so that the insulating cover can be prevented from being corroded under the condition of coastal air.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
